BY084DCS Specifications

  • Dimensions: This shows the name of each dimension and how it is measured in the image.
  • Magnetization Direction: The direction through which the magnet is magnetized. See our Magnetization Directions page for more details.
    Magnetization direction icon Magnetized Through Thickness
  • Size: Size is the physical dimensions of the product using the standard unit of measure inches.
    2 x 0.5 x 0.25 Inch ( Length x Width x Thickness )
  • Metric Size: Metric size is the physical dimensions of the product in metric millimeters.
    50.8 x 12.7 x 6.35 mm ( Length x Width x Thickness )
  • Pull Force 1: Pull force case 1 represents a magnet attracting to a thick steel plate. Learn more about Magnet Pull Force Case 1.
    27.95 lb (12.68 kg)
  • Pull Force 2: Pull force case 2 represents a magnet attracting to a thick steel plate on both sides. Learn more about Magnet Pull Force Case 2.
    68.3 lb (30.98 kg)
  • Grade:
    N42
  • Max Operating Temp: Maximum operating temperature, also known as maximum service temperature, is the temperature at which the magnet may be exposed to continuously with no significant long-range instability or structural changes. Learn more in our Temperature and Neodymium Magnets article.
    176°F (80°C)
  • Material: This lists the name of the material each product is composed of.
    Neodymium (NdFeb)
  • BH Max: BH max is the Maximum Energy Product at the point on the B/H Curve that has the most strength, expressed in MGOe (MegaGaussOersteds). When describing the grade of a neodymium magnet, this number is commonly referred to as the "N" number, as in Grade N52 magnets. Learn more about Bh max in our glossary.
    42 MGOe
  • Tolerances: Dimensional tolerance specifies the allowed leeway for variations in manufacturing.
    ±0.004 in (.1mm)
  • Coating: Most neodymium magnets are plated or coated in order to protect the magnet material from corrosion. Check out our Custom Magnets for unplated magnets and other coatings not stocked for this size magnet. Learn more about all available platings and coating in our What Magnet Coating Should I Use? article.
    Nickel-Copper-Nickel (Ni-Cu-Ni)
  • Weight: This is the weight of a single magnet in ounces and grams. Variety packs (with mixed sizes) show the overall weight.
    1.0723 oz (30.4 g)
  • Br Max: Br max is also called "Residual Flux Density" and is when the magnetic induction remaining in a saturated magnetic material after the magnetizing field has been removed. This is the point at which the hysteresis loop crosses the B axis at zero magnetizing force, and represents the maximum flux output from the given magnet material. By definition, this point occurs at zero air gap, and therefore cannot be seen in practical use of magnet materials. Learn more about Br max in our glossary.
    13,200 Gauss
  • Hole Size: This is the size hardware that best fits the magnet hole size.
    #6 screw
  • Hole Angle: This is the hole angle of the countersunk hole.
    82°
  • Color: The color of the coating or plating on the product.
    Silver

Product Description

The by084dcs double countersunk bar magnet has a 2" length, 1/2" width and 1/4" thickness, has two countersunk holes on each side of the length of the bar that accept #6 screws, is magnetized through thickness and is coated with a nickel copper nickel plating providing a smooth and durable surface that helps protect the magnet from corrosion. Made from N42 grade material, this magnet has a high size to strength ratio and can handle max operating temperatures up to 176°F (80°C).

The by084dcs is a powerful bar shaped magnet that works well in tight spaces where a compact magnet with strong holding force is needed. Its sleek shape and size make it a versatile choice for hobbyists, makers, engineers, designers, and educators working on models and miniatures, 3D-printed parts, crafts, small electronics, prototypes, robotics, hidden closures, and lightweight mounting applications. It can also be embedded into products and enclosures or used to align removable parts and hold small components during assembly.

Common Applications

  • Cabinet & Door Closures - Creating magnetic cabinet, door, and drawer closures.
  • Signs & Displays - Mounting removable signs, displays, and identification panels.
  • Steel Surface Mounting - Attaching fixtures and accessories to steel surfaces.
  • Woodworking Projects - Adding magnetic mounting and attachment to woodworking projects.
  • Access Panels - Securing removable access panels, covers, and enclosures.
  • Tool & Equipment Mounting - Mounting tools, equipment, and workshop accessories.
  • Jigs & Fixtures - Building jigs, fixtures, and positioning systems.
  • Prototypes & Machinery - Creating removable components for prototypes and machinery.
  • Boxes & Cases - Installing magnetic catches in boxes, cases, and storage compartments.
  • Retail Displays - Building retail, trade show, and point-of-purchase displays.
  • Vehicle & Equipment Mounting - Mounting components in vehicles, trailers, and equipment.
  • DIY & Fabrication - Creating DIY home improvement and fabrication projects.

Product Features

  • Rectangular Geometry - Fits naturally into rectangular pockets, slots, channels, and fabricated assemblies.
  • Straight Edges - Makes alignment with edges, corners, and other rectangular components straightforward.
  • Flat Magnetic Faces - Provides convenient face-to-face attachment to magnets and ferrous metal.
  • Countersunk Mounting Holes - Designed to accept flat-head screws for a flush attachment.
  • Mechanical Fastening - Screw mounting provides a more secure installation than relying on adhesive alone.
  • Easy to Remove and Replace - Screw-mounted magnets can be removed, repositioned, or replaced without destroying the mounting surface.
  • Simple Integration - Can be mounted directly to wood, plastic, metal, and other materials that can accept an appropriate fastener.
  • Magnet-to-Magnet Pairing - Opposing countersunk magnets can be used together for removable connections and closures when their poles are properly oriented.
  • Permanent Magnet - Remains magnetized without requiring electricity, batteries, or an external power source.
  • Rare Earth Neodymium Magnet - The strongest type of permanent magnet available, providing exceptional strength for its size.
